Device and method are provided to from excellent to the Session Hand-off of circuit switch cellular systems by IP application programs Change.

With the introducing that single radio continuous voice call is transferred, for example, if user be moved to IP links can not be with The region that guaranteed service quality is maintained, then passing through available some services (such as IMS of IP (Internet protocol) network (IP multimedia subsystem) voice service) can by cellular telephone switching system (such as GSM (be used for mobile communication the whole world System) or UMTS (Universal Mobile Telecommunications System)) continued.In this case, session control is needed from IMS application programs (such as based on SIP's (session initiation protocol)) is seamlessly transferred to circuit switched system call controller.

Device and network can locally manage call session transfer.Synchronism may be not present between the device and the network. During Session Hand-off, by IP connections (or in other words：IP-based connects；Such as sip message) and the certain of transmission exhale Make control signaling (signaling) information that may can not be transmitted due to the suspension (suspension) of device physical layer.It is logical (such as based on UDP's (User Datagram Protocol)) can not often may be identified in IP grades by crossing the signaling of IP, and all Such as IMS " passing through IP " application program possibly can not know not yet to be successfully transmitted to signaling message.This may cause in device IMS application programs and about asynchronous between the IMS service device in the network for the call control state for having shifted session.It is calling After Session Hand-off, the circuit switched call controlled entity in device can not be synchronous with network possibly, leads to poor user Experience, such as longer session establishment or incorrect service setting or the loss of audio.

It possibly can not be fully solved from IMS to the call session for the circuit switched system for using single radio and shift now. 3GPP (third generation partner program) standard, which does not provide, solves the problems, such as this overall mechanism.Currently only cover a kind of feelings Condition (the case where transfer for the calling that UE is terminated in alarm state)：If user receives incoming call, if 200OK (connection) It is sent to IMS network, then after session is independently transferred to circuit switched system, UE will retransmit connection to network (CONNECT) message.

In currently used method and apparatus, IMS application programs possibly can not know, once it is mailed on IP stacks, Whether message is transmitted to network well.Therefore, in Call- Control1 ownership another application is transferred to from an application program In the case of program, the process in transition condition may only fail or from the beginning restart.

It can provide a device that and method, can provide：Due to IMS application programs can be known its critical (critical) The transmission state of signaling message, therefore be also possible even at the call forwarding of transition state.

Exclusive use situation can be only covered according to the device and method of current 3GPP standards, but in call setup process Calling-Session Hand-off has any signaling to exchange in call setup process or has related service (for example, supplement is serviced, exhaled Be meeting and/or DTMF) in the case of problem may occur.In addition, prior art arrangement can be based on " CONNECT " message redundancy (send primary on IMS by IP and sent on circuit switched system second) may be in terms of resource consumption More inefficient.

It can provide a device that and method, IP data-analyzing machines can be introduced to be shifted from IMS application programs in session To checking pending (pending) IP application program signaling messages in the case of circuit switched call controller.

Communication device can provide to protocol stack and be sent to another communication device from communication device and (such as wirelessly be sent out Send or via wired connection) data.Then the protocol stack transfers data to other communication devices using communication protocol.It will Understand, the protocol stack of communications protocol layers may include circuit (or multiple circuits), be configured to be handled with by data from Communications protocol layers including lower level send (for example, the protocol stack of communications protocol layers can provide all layers of communication protocol, Including communications protocol layers and its under each layer).Protocol stack can be agreement stack circuit.

For example, in the case where being shifted by the IMS signalings of LTE, may relate to lower layer：TCP or UDP, IP and bee Following each layers of nest protocol stack.Following each layers can be a part for cellular protocol stack：PDCP (packet data convergence protocol), RLC (radio link controls；It can provide data TM (transparent mode), UM (unacknowledged mode) or AM (affirmation mode, including compared with The instruction of high-rise PDU being delivered successfully) in transfer) and MAC (media access control can manage data transfer and wireless Electric resources distribute).Following services can be provided from PDCP to higher level：The transfer of user plane data；Control plane data turns It moves；Header encapsulates；It enciphers；And globality protection.PDCP can be expected following services from lower level：Confirm data transfer clothes Business, includes the instruction of PDCP PDU being delivered successfully；Unacknowledged data transfer service；It sequentially transmits, is removed in the reconstruction of lower level Outside；And copy is abolished, except the reconstruction of lower level.

Once carrying out the transfer being switched to from packet in the access layer (access stratum) that circuit switches, so that it may which analysis is deposited Store up the IP data in modem-pooling device.In one example, IP analyzers can search the IP data packets not transmitted and It can be provided back to application program, and the application program itself can analyze the content of message.In another example, using journey Sequence can provide " search " pattern to IP analyzers.IP analyzers can provide back the message (such as IP packets) only with pattern match.It will Understand, modem-pooling device may include or can be IP stacks buffer or any cellular protocol stack buffer.IP points Parser can get the feedback whether being successfully delivered about message from lower level.Also can be obtained from lower-level protocols about The input of the reliability of transmission, for example, based on used retransmission protocol (such as MAC (media access control), HARQ (mixing from Dynamic repetitive requests) or RLC (radio link control) ACK (acknowledgement notification)).For example, in the case where data " success " transmits, IP analyzers also can provide reliability indicator to application program.If detecting that (such as SIP believes application program signaling message Enable), then it can notify IMS application programs and then can determine whether the accurate status of call session to be transferred (multiple sessions).Cause This, IMS application programs can indicate the accurate status of call session (multiple sessions) to circuit switched call controller.Electricity The exact point that road switching call controller can be then able to be stopped from current sessions continues as current sessions and carries out signaling, i.e., Make in transition stage to be also such.

This allows to be led to during call session is transferred to circuit switched system by the application program of IP connection work Know the signaling critical messages not transmitted.

It is correct that described device and method, which can provide the call session transfer switched from IMS to circuit, this can reduce net The risk of the poor synchronism of network.Therefore, any user's request can have the relatively good opportunity that will be successfully executed, and provide preferable use It experiences at family.

Due to known accurate call state, described device and method allow to be easier to circuit switched call controller Management allows to continue directly to session without handling additional retransmitting message or error situation.It can be based on existing 3GPP standards It realizes the execution of the process in transition state, and optionally can further be improved by being made a change to 3GPP standards The execution of journey.

Described device and method can provide higher effect because avoiding message redundancy degree in the signaling with network exchanges Rate.

Described device and method can be applied to all processes (such as sound/video call session signaling and/or supplement clothes Business) signaling and the additional signaling between device and network can not needed.Device and method can be provided and make initial call control Device processed can get about which message by accurately (the affirmation mechanism reliability based on lower level have potential uncertainty Successfully) the accurate status sent, such as message are sent from cellular protocol stack.

Therefore, call session signaling status (such as communication session, for example, call session state or situation) using shifting Friendship process is transferred to another Call- Control1 to device.Second Call- Control1 then can be from the standard indicated by the first Call- Control1 It really lights and continues call session signaling.From this position, it is able to continue and can be well defined with the signaling of network, In other words it can be specified well.In addition, it is possible to provide error handle.In order to be supported to this, it is possible to provide clear in 3GPP Clearly to indicate that this transition is possible.

According to various device and method, signaling may specify the new signaling of network, wherein after the handover, UE can be defined Ground sends the signal of its state or position to help network successfully to continue the process.This can be specified in 3 gpp.

Device and method from packet switching connection hand over to circuit switching connection in the case of can be based on be embedded in IP packets (or The packet of any other type from another protocol layer) in the lookup and retrieval for not shifting session control message.This information can It is used for the accurate Call- Control1 transfer from IMS application programs to circuit switched system call controller.This is then It can be used for retransmitting unacknowledged signaling information.

It can provide a device that, may include packet buffer analyzer, which can find Application program signaling message in IP/L2 data buffers.Internal buffer can be carried out by any of multiple components In pending data analysis (component analyzed is referred to alternatively as message analysis device, such as control message analyzer, such as It may be provided in cellular protocol stack；Such as cellular protocol stack can analyze the not yet successful data stored transmitted；Alternatively, for example Individual module can analyze stored IP bag datas；Alternatively, for example stored data can be sent back to transmitter applies journey Sequence (such as IMS components) so that then application program its own can be analyzed).In order to make application program analysis be easy, at Reliability indicator can be provided in the case of work(transmission (such as message that is last or hereafter sending).In order to make IP data point Analysis is easy, and can provide pattern by application program to identify critical signaling message.Analysis mechanisms can be configurable, in session Ownership from application program be transferred to circuit switched system conversation controller in the case of application program may indicate that only progress IP numbers According to analysis.

It can provide a device that and method, can be provided to request applications and be present in being deposited in data buffer Store up the report of signaling message.To send the trigger of report can be configurable, such as from IMS to circuit switched system SRVCC (or SR-VCC；Single radio tone calling continuity) transfer complete when can touch trigger.

The information reported can be used for the accurate transition state for judging service conversation and enhance different sessions controller Harmony between (such as IMS and circuit switched system).

Various examples are described for cellular protocol stack (CPS) although will be appreciated that, CPS can in each example To be any protocol stack, such as WLAN (WLAN) protocol stacks or bluetooth protocol repertory, such as transmission channel is provided, such as with In any protocol stack of the agreement of IP communications.

Fig. 4 shows the flow chart 400 of the Session Hand-off for the calling for showing that the UE under foundation is initiated.It is shown in Fig. 4 In the mobile call session transfer for initiating calling, it is shown that the user 402 of communication device, the IMS application programs 404 of communication device (its be also referred to as " IMS " 404), the CPS 406 of communication device, LTE or IMS NW408 and UMTS or GSM NW410 it Between communication.It will be appreciated that LTE network and IMS network can be individual networks.The NAS layer entities of CPS can be with LTE MME dialogues in (EPC (evolution packet core)) core network, but IMS layers can be with its dialogue at the same level in IMS core network. For convenience of description, LTE and IMS can be shown in figure to be combined in a box.But different signaling messages do not reach Identical entity in network.In 412, user 402 can send cell setting request to IMS 404.IMS 404 can be to LTE/ IMS NW 408 send SIP INVITE 414.LTE/IMS NW408 can send 100 to IMS 404 and attempt message 418.LTE/ IMS NW408 can send message 420 during 183 sessions carry out to IMS 404.LTE/IMS NW 408 can send 180 to IMS 404 Ringing message 422.In 424, it will be assumed that LTE coverage areas may be bad, and NW may indicate that the transfer of GSM.426 In, LTE/IMS NW can send 200OK signals to IMS 404.In 428, LTE/IMS NW 408 can send to CPS 406 and move Hand over order to start SR-VCC programs.(in other words, IMS 404 can send ack signal 430 via CPS 406 to IMS network IMS 404 can utilize the transport protocol of cellular protocol stack to send ACK to IMS network), but the signal can be assumed to be arrival network And one in the transmission buffer as the user plane (such as CPS 406 or more) that " X " is indicated in Fig. 4 can be rested on In, such as because PHY (physical layer) is suspended in 434." X " can refer to message and not be successfully delivered to network or do not receive come The instruction (for example HARQ ACK in MAC layer) of automatic network (it indicates successfully to transmit).IMS 404 can be sent out to user 402 Send call connected signal 432.CPS 406 can send SR-VCC to IMS 404 and start indication signal 436.The NAS layers of CPS can be to IMS notice SRVCC programs are activated and the control of call session can be transferred to CPS.In 438, for IMS application programs For, it can successfully carry out call setting.IMS application programs may be unaware of SIP ACK and not be successfully delivered, because by message It posts to after IP stacks, packet may be notified and transmitted well.However, message may lower level (such as 440) it is prevented from.When transferring beginning, the physical layer of source RAT (radio access technologies) may be suspended for allowing in target Synchronization on RAT.Therefore, it is possible not have message exchange for network.CPS 406 can be to UMTS/GSM NW 410 It sends to transfer and completes signal 442.CPS 406 can send SR-VCC to IMS 404 and complete instruction 444 to trigger the control of calling Transfer.

The processing as shown in box 446 may indicate that the problem caused by the processing according to existing standard.448 In, call session transfer signal can exchange between IMS 404 and CPS 406.In 450, CPS can be notified that movable calling Session.452 may indicate that IMS NW 408 never receive ACK and possibly can not judge whether UE receives 200OK (connection) 426.Network is believed that the failed connection of service (after certain timers expire), this can lead to the release of call session.Phase Instead, in the case where UE does not receive 200OK, network is believed that calling has connected, but UE may still wait for connection to indicate.So And this is only an example for behavior.Actual behavior may depend on web implementations.Or NW can be dependent on Then ACK may make certain decisions or network in the case where not receiving ACK can be independent of ACK and then can be independent Judge whether UE obtains 200OK.In this way, the network behavior for being transferred to GSM/UMTS MSC (mobile handoff center) about calling can Can be unknown.UE can not be synchronous with NW possibly.It is successfully attached for example, this may be calling to the impression of user, and Not actually in this way.

Shown in box 454 processing show by may be provided with for example IP data-analyzing machines (such as Fig. 9 to scheme Described in 12) processing that is provided of device and method.456 show that the pending data in IP/CPS buffers is analyzed.Such as Fruit detects SIP signaling messages, then can provide feedback.In 458, CPS 406 can send the SIP letters detected to IMS 404 Enable message, such as SIP ACK messages.Once completing to transfer from the angle of access layer, then Call- Control1 can be transferred to CPS from IMS NAS.In order to complete in a reliable fashion, IP analyzers (regardless of its position) can provide potential pending IP to IMS components Packet or SIP signaling messages (two kinds of embodiments are equally possible).As example, IP analyzers can be a part of CPS simultaneously And the IP packets containing sip message 200OK can be detected in transmission buffer.Then this can be indicated pending to IMS components 200OK.Then IMS can determine whether accurate call state and can proceed with call session transfer.460 may indicate that IMS 404 The call session transfer signal exchanged between CPS 406, this can provide calling and have connected, and will send connection confirmation and disappear Breath.UE behaviors are now based on more accurately calling transition state.If receiving 200OK, but ACK is sent not successfully, then UE can Connection is sent to confirm to avoid in any ambiguity of network side.It also can ensure that, UE is not believed that in connection status, and network Still think that UE is in alarm state.(really otherwise, UE can receive come automatic network connection instruction, and its connected it is potential Ground is considered as abnormal case).In 462, connection, which confirms, to be sent to UMTS/GSM NW 410 from CPS 406.460 and 462 can To be new behavior and can describe in 3 gpp.

Fig. 5 shows the flow chart 500 of the Session Hand-off for the calling for showing that under foundation, the UE of (precaution alarm state) is terminated. Fig. 5 is shown in the SRVCC processes started during warning stage (Mobile Termination) call session.In Figure 5, it is shown that The user 502 of communication device, CPS 506, the LTE of IMS application programs 504 (it is also referred to as " IMS " 504), communication device Communication between IMS NW (network) 508 and UMTS or GSM NW 510.It will be appreciated that LTE network and IMS network can To be individual network.The NAS layer entities of CPS can talk with the MME in LTE (EPC (evolution packet core)) core network, but IMS layers can be with its dialogue at the same level in IMS core network.For convenience of description, LTE and IMS can be shown in figure as by group It closes in a box.But different signaling messages does not reach the identical entity in network.In 512, LTE/IMS NW 508 SIP INVITE signals can be sent to IMS 504.In 514, IMS 504 can send 100 to IMS NW 508 and attempt signal. In 516, IMS NW 508 can send signal during 183 sessions carry out to IMS 504.It may be assumed that in 518, LTE coverage areas are not It is good, and NW may indicate that the transfer of GSM.In 520, LTE/IMS NW 508, which can start SR-VCC, to be transferred and is ordered transferring Order is sent to CPS 506.It may be assumed that in 522, PHY layer is suspended.In 524, IMS 504 can be sent to IMS NW 508 180 ringing signals, but as indicated by " X " in Fig. 5, which possibly can not reach network；For example, by communication device The message that sends of IMS components 504 possibly can not reach network.In 526, IMS 504 can send incoming call to user 502 Signal.In 528, CPS 506 can send SR-VCC to IMS 504 and start to indicate.Box 530 may indicate that for IMS, exhale It cries in alarm state.Box 532 may indicate that the IP packets including 180 jingle bell 524 of sip message due to hand-over and be buffered in IP It is prevented from device or cellular protocol stack PS buffers.In 534, CPS 506 can send to transfer to UMTS/GSM NW 510 and complete Signal.

The processing as shown in box 536 may indicate that the problem caused by the processing according to existing standard.538 In, CPS 506 can indicate that hand-over is completed and the control of call session will be transferred to CPS from IMS 504 to IMS 504 506.(it may indicate that calling is in alarm to the call session transfer signal that 540 instructions exchange between IMS 504 and CPS 506 Stage).Box 542 may indicate that CPS 506 is notified MT (Mobile Termination) calling in alarm state.Box 544 can refer to Show that IMS NW never receive 180 jingle bells 524 and are believed that calling is not yet in warning stage, and can turn in call session Service is abandoned after moving.UE can not be synchronous with NW possibly.Calling can be maintained certain time but have unpredictalbe behavior.

Shown in box 546 processing show by may be provided with for example IP data-analyzing machines (such as Fig. 9 to scheme Described in 12) processing that is provided of device and method.In 548, CPS 506 can send SR-VCC completions to IMS 504 and refer to Show.In 550, pending data that can be in analyzing IP/CPS buffers.If detecting SIP signaling messages, feedback can be provided.
